That ASUS panel is a good choice I reckon for gaming. especially if you are going the one card route...
Thing about panel types is that one type is good for one thing but a bit worse for another.
The fast 2ms panels are usually TN types that are fast and therefore better for gaming and probably 3D but not so good on the colour accuracy side of things. IPS panels usually have slower response times but are better for color...
I have IPS because I value color over gaming because I like photography etc. but the screen is perfectly good for gaming too.
But if your priority is gaming and especially 3d then a TN panel with high refresh rate and fast response time will probably be your choice and of course the colors are going to be good just not Photoshop-graphic-art-pro good.
